<u>Answer:</u>
<em>That oxidation number of chlorine is -1 while that of oxygen is -2</em>
<u>Explanation:</u>
When it comes to manganese chloride to stabilize the chlorine Ion. Two manganese ions shall be required. Hence the formula for the compound becomes
while the formula for manganese (iv) chloride will be
similarly.
When oxygen and magnesium oxide is considered the Two ions of Manganese will satisfy to ions of oxygen. Which cancels and becomes
while for manganese (iv) oxide the formula becomes
.
